variety of tetra-substituted pyrrole derivatives were synthesized through one-pot four-component condensation reaction of aromatic aldehydes, benzylamines, β-ketoesters, and nitroalkanes in the presence of 10 mol % NiCl2·6H2O in good yields. Some of them exhibit properties as potential inhibitors of phosphodiesterase 4B (PDE4B) through docking studies.

A faster and efficient synthesis of polysubstituted pyrroles has been achieved via a four-component reaction from beta-ketoesters, benzylamines, aromatic aldehydes, and nitromethane in the presence of Amberlyst-15 under ultrasound. A variety of pyrrole derivatives were synthesized by this simple and straightforward methodology in good yields. (C) 2013 Elsevier Ltd. All rights reserved.
